GCSE Biology Topics: What You Need to Know for the Exam

Introduction

 

GCSE biology can be both inspiring and challenging for students. There are a number of topics to revise for the exam, so to help you get organised, we’ve put together this useful guide. You’ll find a list of all the GCSE biology topics in this article.

 

There are seven main subject areas covered in the exam, split across two separate papers:

 

  1. Cell biology
  2. Organisation
  3. Infection and response
  4. Bioenergetics
  5. Homeostasis and response
  6. Inheritance, variation and evolution
  7. Ecology

 

Paper one covers topics 1-4: cell biology; organisation; infection and response and bioenergetics.

 

Paper two covers topics 5-7: homeostasis and response; inheritance; variation and evolution; ecology and key ideas.

 

Each paper lasts one hour and 45 minutes and is made up of multiple choice, structured, closed short answer and open response questions. For more information on the GCSE biology test format, please visit the AQA website.

 

Each of these eight subject areas are broken down into a variety of topics that students might be assessed on come exam day. You can find more information about each of these topics below:

The Best Way to Revise GCSE Biology Topics 

 

Biology is the study of life and living organisms, which teaches us all about humans and our surrounding environment. The skills students can learn in biology are transferable and can be applied practically to everyday life. When starting your revision for GCSE biology, make (and stick to) a revision plan. Make space for each topic outlined above, so you know you’re fully prepared for whatever questions might be asked in the exam.

 

GCSE biology is a content-heavy subject, so it’s important to summarise your notes to make it easier for you to revise. Use visual aids, rewrite notes using colour, use bullet points or different strategies that best suit your learning needs.

GCSE Biology Practice Tests

 

Our GCSE biology revision packs can help students become familiar with question command words. Understanding what the question is asking you will help to structure your answers and achieve the highest marks possible.

 

Our biology packs cover all eight topics in the GCSE biology syllabus and have been created by former GCSE biology examiners. As part of the process of creating our packs, we thoroughly analysed examiners’ reports from previous years to ensure we have every question type covered. To prepare you for every eventuality, we’ve even included some of the most difficult questions that you’re likely to come up against in the exam.

 

When using our GCSE revision papers, we highly recommend timing yourself, to ensure that you complete the questions and exam papers in the required time. Our practice paper questions cover all the essential areas of the exam and are written and developed by former GCSE biology examiners and markers.
